Description
LV_TTL input that opens switches that disconnect the driver
and comparator from VIO. This input overrides the individual
switch register bits non destructively.
Device input/output of each channel.
or low level.
active or in a high impedance state.
driver high and low levels. Connect a 0.22µf capacitor to
ground for bypassing reasons.
0.47 µF capacitor to ground for bypassing reasons.
PMU test point for the anode of the thermal diode string.
Parametric Measure Unit input/output of each channel.
External parametric measurement for force input.
External parametric measurement for sense input.
Pull-up voltage input.
Continuity test circuit limit voltage.
Continuity test circuit force current voltage.
Active low chip reset. Resets the internal registers. It is an
asynchronous input not requiring any CLKIN transitions.
Clock for the input data shift register.
Serial data input.
Serial data out.
Loads input data into central register.
